Oracle als ODBC-Datenquelle Excel 2010 - der SQL-Pass-Through

Excel ist das neben Word vermutlich am weitesten verbreitete Office-Produkt in Unternehmen sowie auf privaten Rechnern. Und Excel hat schon sehr umfangreiche Funktionen. Interessant und knifflig wird es aber, wenn man auf Daten aus einer Datenbank (Oracle) zugreifen möchte. Erforderlich hierfür ist eine eingerichtete ODBC-Datenquelle.
Über das Menü "Daten", Untermenü "Aus anderen Quellen", Eintrag "Von Microsoft Query" kann man nun über den sog. DSN und Microsoft Query Daten aus der Datenbank abrufen. Möchte man aber eine proprietäre Oracle-Abfrage formulieren, wird Microsoft Query die Anfrage nicht verarbeiten könnnen. Der dafür liegt in der Vorverarbeitung der eingegebenen Statements. In Query selbst gibt es keine Möglichkeit, dies zu umgehen - in Excel selbst schon. Daher wählt man über eine "Dummy"-Abfrage einige Daten aus und manipuliert das SQL-Statement postwendend. Im abschließenden Query-Dialog wählt man "Daten an Excel zurückgeben" und klickt auf "OK".

Im Excel-Dialog "Daten importieren" (im Anschluss) klickt man nun auf "Eigenschaften".

Es öffnet sich der Dialog "Verbindungseigenschaften". Über den Reiter "Definition" kann man im Feld "Befehlstext" nun das proprietäre Oracle-Statement eingeben.

So werden sogar Abfragen mit TABLE-Function möglich.

Pi And More 11 - QMC5883 Magnetic Field Sensor Class

A little aside from the analytical topics of this blog, I also was occupied with a little ubiquitous computing project. It was about machine learning with a magnetic field sensor, the QMC5883. In the Arduino module GY-271, usually the chip HMC5883 is equipped. Unfortunately, in cheap modules from china, another chip is used: the QMC5883. And, as a matter of course, the software library used for the HMC5883 does not work with the QMC version, because the I2C adress and the usage is a little bit different. Another problem to me was, that I didn't find any proper working source codes for that little magnetic field device, and so I had to debug a source code I found for Arduino at Github (thanks to dthain ). Unfortunately it didn't work properly at this time, and to change it for the Raspberry Pi into Python. Below you can find the "driver" module for the GY-271 with the QMC5883 chip. Sorry for the bad documentation, but at least it will work on a Raspberry Pi 3.

How to use TOracleConnection under Lazarus for Win64

Lazarus Programmers have had no possibility to use TOracleConnection under 64 Bit Windows and Lazarus for years. Even if you tried to use the TOracleConnection with a correctly configured Oracle 11g client, you were not able to connect to the Oracle Database. The error message was always: ORA-12154: TNS:could not resolve the connect identifier specified Today I found a simple workaround to fix this problem. It seems like the OCI.DLL from Oracle Client 11g2 is buggy. All my attempts to find identify the error ended here. I could exclude problems with the TNS systems in Oracle - or the Free Pascal file oracleconnection.pp though the error messages suggestes those problems. After investigating the function calls with Process Monitor (Procmon) I found out, that even the file TNSNAMES.ORA was found and read correctly by the Lazarus Test applictaion. So trouble with files not found or wrong Registry keys could also be eliminated. Finally I installed the Oracle Instant Client 12.1c - aft

Lazarus IDE and TOracleConnection - A How-To

Free programming IDEs are a great benefit for everybody who's interested in Programming and for little but ambitious companies. One of these free IDEs is the Lazarus IDE . It's a "clone" of the Delphi IDE by Embarcadero (originally by Borland). But actually Lazarus is much more than a clone: Using the Free Pascal-Compiler , it was platform-independent and cross-compiling since it was started. I am using Lazarus very often - especially for building GUIs easily because Java is still Stone-Age when a GUI is required (though there is a couple of GUI-building tools - they all are much less performant than Delphi / Lazarus). In defiance of all benefits of Lazarus there still is one Problem. Not all Components are designed for use on a 64 bit systems. Considering that 64 bit CPUs are common in ordinary PCs since at least 2008, this is very anpleasant. One of the components which will not be available on 64 bit installations is the TOracleConnection of Lazarus' SQLDB
